Frequently asked questions

Why do pen needle lengths come in 4, 5, 6, 8 and 12 mm?

Length is chosen to reach subcutaneous tissue reliably without reaching muscle. Short 4 mm needles have largely replaced longer lengths for adults because they reduce the risk of intramuscular injection.

Should a pen needle be reused?

No. Reusing a pen needle blunts the point, increases pain and can affect dose delivery. Facilities usually issue needles per injection and drop each one into a sharps container.

Do pen needles fit every insulin pen?

Pen needle platforms differ. Verify compatibility against the specific pen model you stock before setting a standard.
